Abstract

A portable light including an elongate body having a hollow frame and a longitudinal axis extending through the hollow frame, and an extension pole slidably received within the hollow frame. The extension pole is movable between an extended position, in which the extension pole is at least partially positioned out of the elongate body, and a retracted position, in which the extension pole is at least partially positioned in the elongate body. The portable light further includes a light assembly coupled to an end of the extension pole. The light assembly includes a base, a center column coupled to the base, and a plurality of light heads disposed around the center column, where each of the plurality of light heads are independently pivotable relative to the center column about a light axis that is perpendicular to and offset from the longitudinal axis. The portable light further includes a collar positioned around a portion of the elongate body and a plurality of legs pivotably coupled to the collar. The light heads are pivotable about the light axes from a default position, in which the light heads surround the center column and emit light in the same direction, to a deployed position, in which the light heads emit light in different directions. The light heads are equally spaced circumferentially about the longitudinal axis by approximately 120 degrees.
